as we all know, China's mobile communication technology is only a follower in the 2G era, but now in the process of 5g standard formulation, whoever adopts the standard will have more say in the future 5g development. At present, Europe, the United States and China are competing for 5g standard voice. According to the latest report, what's the matter with 5g Lenovo voting for Qualcomm? How did 5g Lenovo vote for Qualcomm?
In 2017, 3GPP (International Organization for Telecommunication Standardization) determined the polar code dominated by Huawei and other Chinese enterprises as 5g control channel coding scheme, which once led the media to think that Huawei had crushed Qualcomm, and 5g in China completely ended the excessive interpretation of Western standards. However, the actual polar code selection is only a small step of 5g standard, and there is still a long way to go for the right to speak.
However, in the process, it was reported that Lenovo voted for Qualcomm's camp in the key vote of 5g standard and against the Chinese Camp represented by Huawei. In response, Lenovo said that Lenovo voted for the 5g standard polar scheme (the scheme is dominated by Chinese enterprises such as Huawei and China Mobile), including Motorola mobile, which is owned by Lenovo, all voted in favor.
As for why Lenovo voted against, Netease technology looked for 86-87 minutes of 3GPP. It found that Lenovo had voted for the LDPC standard of Qualcomm camp in the data channel standard (86B meetings), but Lenovo voted for polar in the follow-up meeting (87 meetings), but polar still lost to LDPC in the data channel.
3GPP defines three scenarios of 5g: embB: 3D / ultra high definition video and other large flow mobile broadband services; mmtc: large scale Internet of things services; and urllc: services requiring low delay and high reliable connection, such as unmanned driving and industrial automation.
Each camp has formed a fierce competition for the standards in the embB scenario. There are mainly three coding camps: LDPC in the United States represented by Qualcomm; polar in China represented by Huawei; turbo2.0 in Europe represented by Ericsson.
Some media said that Lenovo's key vote on 5g standard led to the failure of polar supported by Chinese enterprises including Huawei. In response, Lenovo said that at the 5g standard voting conference held by 3GPP (generation partnership project), Lenovo voted for the 5g standard polar scheme (the scheme is dominated by Chinese enterprises such as Huawei and China Mobile), including Motorola mobile, which is owned by Lenovo, all voted for it. And the rumors outside are more rumors.
The voting process of "couchetard" sharing from Zhihu shows that Lenovo opposed polar in data channel at 86B meeting, but because the meeting did not discuss the final result of 5g short code, the voting was meaningless; in 87B meeting, Lenovo supported short code polar technology, but ultimately polar was transmitted to LDPC in data channel short code, but in control channel coding, P Olar won over LDPC.
For this reason, Netease technology also inquired the 3GPP meeting record process, which is indeed the process.
Lenovo did not vote in favor of Chinese enterprises. People who have been involved in 5g standard told Netease technology that 3GPP is a technology-oriented organization. What standard data channel and control channel should be selected depends on theory, simulation data and practical implementation difficulty, etc. There is no so-called problem of standing in line. The leading or equivalent of 5g standard is the result of joint efforts of many companies, and Lenovo has also made its own contribution.
